Answer:
4 and 9
Step-by-step explanation:
let their ages be x and x - 5, then in 4 years their ages will be
x + 4 and x - 5 + 4 = x - 1 , and the product is 104, thus
(x + 4)(x - 1) = 104 ← expand factors on left using FOIL
x² + 3x - 4 = 104 ( subtract 104 from both sides )
x² + 3x - 108 = 0 ← in standard form
(x + 12)(x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 12 = 0 ⇒ x = - 12
x - 9 = 0 ⇒ x = 9
However, x > 0 ⇒ x = 9
Thus
Their present ages are 9 and 9 - 5 = 4

Jose bought 750 bags for $375.00
Each bag cost $375/750= $0.50
He intends to sells them for $0.15 more
He should charge : $0.5 +$0.15=$0.65
Answer:
6,1

Answer:
Step-by-step explanation:
The square has 4 sides with length 4
The right triangle has the right side equal to 4yd + 4yd(from the square) = 8yd
Using the Pythagorean Theorem, we find that the left side of the triangle has length = 10yd
The area of the whole thing is the area of the square + the area of the triangle
The formula for the area of a square with sides l is
The area of the triangle is trickier, but you can imagine tracing a line in the left side and the upper side to form a rectangle, and the area of that is A = , the area of the triangle will be half the area of the rectangle so it'll be
The total area will be;
Area of the square + Area of the triangle =
The arrow's maximum height above the ground can be calculated using maximum height. The maximum height reached from the launch point is 1024 feet. Adding the height of the building, the overall maximum height of the arrow is 1,109 feet.
To find the maximum height of the arrow, you can use the following formula:
Maximum Height = Initial Height + (InitialVelocity^2 / (2 * Acceleration due to gravity))
In this case:
Initial Height = 85 feet
Initial Velocity = 256 feet per second
Acceleration due to gravity (approximated as 32 feet per second squared)
Maximum Height = 85 + (256^2 / (2 * 32))
Maximum Height = 85 + (65536 / 64)
Maximum Height = 85 + 1024
Maximum Height = 1109 feet
So, the maximum height the arrow reaches above the ground is 1,109 feet.

The image of the point after a reflection over the y-axis is (-2, -1)
From the question, we have the following parameters that can be used in our computation:
Point = (2, -1)
Transformation rule
A reflection over the y-axis
The rule of a reflection over the y-axis is
(x, y) = (-x, y)
Using the above as a guide, we have the following:
Image = (-2, -1)
Hence the image of the point after a reflection over the y-axis is (-2, -1)
